The glass of 1 mm thickness absorb 4% of UV radiation passing through. How many percent of UV rays absorb glass with a thickness 1.1 cm, made from 1 mm thick those glasses?

Result

x =  36.2 %

#### Solution:

$q = 1-4/100 = 0.96 \ \\ x = 100\cdot (1-q^{ 11 }) = 100\cdot (1-0.96^{ 11 })= 36.2 \% \ \\$

Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
